Acute symptoms and subsequent post-acute symptoms following COVID-19 vaccination: A Danish population-based study Objectives Acute symptoms are common following COVID-19 vaccination, yet it remains unclear if these reactions can manifest or progress into non-specific symptoms (e.g., headache...

Beneficial Effect of COVID-19 Vaccination on Decreased Pulmonary Vascular and Airway Volumes of Patients with Long-COVID Syndrome BACKGROUND Despite normal lung imaging and preserved pulmonary and cardiac function, many patients with long COVID continue to experience persistent respiratory...

COVID-19 vaccination timing, relative to acute COVID-19, and subsequent risk of long COVID Summary Background Vaccination is a vital tool in preventing acute COVID-19 and may confer additional protection against Long COVID, although it is unclear whether this protection wanes over time...

Immune correlates underlying small fiber neuropathy presenting as vaccine-associated post-acute SARS- coronavirus syndrome BACKGROUND A spectrum of adverse events overlapping with Post-acute Sequelae of SARS-CoV-2 infection (PASC) occurs in some patients following SARS-CoV-2 vaccination...

Persistent class switch toward spike-specific IgG4 antibodies after repeated SARS-CoV-2 mRNA vaccination in post-acute infection syndrome: an exploratory cohort study Ana M. Espino, Carlimar Ocasio-Malavé, Riseilly Ramos, Ramon Sanmartin, Jesus Castro-Marrero Abstract Myalgic...

Autoimmune Disease is Associated with Heightened Long COVID Risk but Prior Immunization is Protective Objectives Patients with autoimmune disease (AD) may be predisposed to Long COVID, yet the impact of primary autoantibody-associated AD and prior immunization remains unclear. Methods...

Adenoviral Inciting Antigen and Somatic Hypermutation in VITT BACKGROUND Vaccine-induced immune thrombocytopenia and thrombosis (VITT) is a rare prothrombotic complication that occurs after adenoviral vector–based vaccination against coronavirus disease 2019; in rare cases, it can also occur...

Immunological Density Shapes Recovery Trajectories in Long COVID [Line breaks added] Abstract Post-acute sequelae of SARS-CoV-2 infection (Long COVID) frequently persists for months, yet drivers of clinical remission remain incompletely defined. Here we analyzed 97,564 longitudinal PASC...
